STRAP BUCKLE Filed Feb. 5, 1930 July 15, 1930.

Fatemi-etiL July 15, 1930 tutti sr PATENT r (tirT12-rica CHARLES F. LEMCKE, 0F MILWAUKEE, W'ISGONSIN, ASSIGNOR 0F ONE-HALF TO JOHN A. JOHNSON, OF MILWAUKEE, WISCONSIN STRAP BUCKLE Application filed February 5, 1930.y Serial No. 426,042.

This invention relates to improvements in strap buckles.

One of the objects of my invention is the provision of an improved type of buckle particularly adapted for use on supporting straps on clothing and straps similar to that type which are used on overalls with the bottom engaging loop connected with the buckle so that this loop can be quickly and readily adjusted along the supporting strap, and the buckle is so constructed that it can be quickly and easily attached or detached, and when in an applied posit-ion will securely grip the material of Vwhich the strap is formed so as to reduce the chances of the slipping of the buckle on the strap.

Another object of my invention is the provision of a hinged type of buckle whereby the parts may be quickly and readily supported to permit the removal of the buckle from a strap to which the same is attached and isprovided with means whereby the buckle will be securely held against movement relative to the strap when the same is applied in clamping position to the strap.

Vith the above and other objects in view, the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and sho Wn in the accompanying drawings wherein:

lFigure l is a top plan View of a buckle constructed in accordance with my invention;

Figure l is a bottom plan View;

Figure 3 is a longitudinal section taken on the line 3 3 of Figure l; and

Figure 4 is a transverse section on the line 4-4 of Figure l.v

ln the construction of my improved Y buckle, I provide a frame 1 rectangular in form, as illustrated, and which is construct` i ed of a single piece of comparatively heavy wire and mounted upon this frame 1, is the base plate 2 of my improved buckle. The base plate is formed of sheet metal of suit` able width and length with its longitudinal sides rolled around the longitudinal sides of the frame' l, as indicatedv at 3, thus securely fastening plate 2 to the frame. The base plate 2 is provided with a plurality of punched out places 4 which form a plurality of penetrating points 5 upon the clamping face of the plate, said penetrating points being adapted to enga-ge the material of a strap or other member to which the buckle is applied, so that when the base plate is clamped to the strap, the points or prongs will prevent slipping of the buckle on the strap.

ln order to securely clamp the base ,plate 2 to a strap or the like, I provide a clamping plate 6, one end ofwhich is provided with a tongue adapted to' have its outer extremity provided with a loop 7 which embraces one end of the frame l, as shown in Figure 3, to hingedly connect the clamping plate 6 to the frame. f y

The tongue which is provided at o-ne end of the Vplate G extends laterally of the plate, as shown at 8, thus providing, when the buckle is clamped to a strap, suitable space for the reception of the strap between the two buckle members.

The end of the clamping plate ldopposite its hinge point kis provided with a longitudinalextending tongue having an outwardly curved portion 9 at its outer end to form a retaining shoulder. Pivotally mounted upon the end of the frame l opposite the vsleeve 7 isa U- shaped clampingmember l0, the ends of whichare provided with eyes 11' adapted to be looselymounted upon the end of the frame l, while the intermediate portion thereoir is so arranged as to screw upwardly over the arcuate portion 9 on the tongue of the clamping plateV 6 and engaged behind ythis arcuate portion for retaining the plates 2 and 6 in relative clamping position.

`l/lvhenever the buckle or clamping device is used in connection with 'the supporting straps of overalls and the like, a-loop engaging member l2 is provided, ythe ends of which are loosely mounted upon one of the side portions of the frame, as shown in Fi ures l and 2, so that the button engaging loop l2 can be readily moved to various positions for engaging a supper-ting button or the like.

The clamping'plate isprovided with a proximately the central yprongs plurality of punched out places 13 forming a number of penetrating prongs 14 which are arranged in opposed relation with the on the base plate 2.

In punching out the openings 14 and 13 in th'ewtyro opposed plates, it is preferred to haveopenings in one of the plates arranged spaced parallel relation as shown ln igure 2, which in the present instance represents thebottoln or base plate 2, While a single longitudinalline of openings is punched out in the clamping plate at apso that the prongs 14 will be arranged between the prongs 5, thus providing a greater clam ing surface than if the prongs were Uilm! ed out of only one plate, as is usually the case with buckles in this type.

the attaching of this buckle to fabric straps or the like, the intermediate portion of the Ufshaped member is disengaged from the tongue at one end of the clamping plate and the clamping plate swung outwardly to permit the positioning of the strap between the base plate and the clamping plate. The Clamping plate 6 is then urged downwardly toward thebase plate until the U-shaped clamping member 10 can be moved upwardly over the arcuate portion 9 of the tongue of the clamping plate and in `this manner, it willbe noted that the prongs 5 and 14 will be urged into penetrating position relative to the strap to which the buckle isapplied, so esito securely hold the buckle in position and prevent any sliding movement of the buckle on the strap.

While I have shown and described the body engaging loops 12 as applied to the frame of the buckle, it will be apparent that various other types of supporting elements may be used in connection with my improved buckle and the buckle in itself is of such construction that itcan be manufactured at a very low cost and the effective operation of the device is such that a strap of almost any material can be securel clamped between the two members 2 an 6,-'sothat the penetrating prongs 5 and 4 will prevent any sliding movement of theibuckle on the strap.

While I have shown and described the preferred embodiment of my invention, it will he apparent that slight changesmay be made in .the construction when putting the invention into practice without departing from thespirit of the same or the scope of the appended claim.

In a buckle of the class described, a substantiallyrectangular frame, a base plate having its longitudinal edges embracing the sides of the frame,rpenetrating lugs carried b i theibase plate and extending at one side tllel'efea clamping plate pivotally connected at one end to one end of the frame, penetratng fluege carried by the clamping plate portion of the plate consin.
